The Chequamegon-Nicolet National Forest, which covers more than 1.5 million acres in northern Wisconsin, announced Thursday it was delaying the opening of all recreation sites and campgrounds until further notice.

The forest service said they will continue to monitor the situation and will reopen sites on a case-by-case basis.

“Personal responsibility is now more important than ever. Let’s all do our part to ensure we are keeping ourselves, our families and our communities safe by being prepared and recreating responsibly,” Paul Strong, forest supervisor on the Chequamegon-Nicolet National Forest, said in a release.

The forest service reminded people to follow social distance and personal hygiene guidelines if they visit the forest, as well as leave-no-trace principles which include carrying out all trash and planning to use the restroom before or after visiting.
